Battlemage on Luminark of Hysh

Each time this unit attacks with its Searing Beam of Light, pick a point on the battlefield within range to be the target. If the attack scores a hit, draw a straight line between that point and the closest point on this unit’s base. Inflict D3 mortal damage on each visible unit (friendly and enemy) that the line passes across.

Friendly Cities of Sigmar units have Ward (6+) while they are wholly within 12" of this unit.
